*Risk Classification: Forests where < 0.5 kg/ha DDT was applied tend to have lakes with brook trout that reflect low DDTs.
Brook trout from lakes where > 1.0 kg/ha DDT was applied tend to reflect higher DDTs (see Kurek et al. 2025 PLoS One).
Risk is based on the protection of wildlife consumers of aquatic biota, such as birds of prey, NOT humans (Canadian Council of Ministers of the Environment 1999).
The levels detected in brook trout from the study (Kurek et al. 2025 PLoS One) were below Health Canada Maximum Residue Limits (MRL) for human health and food safety for the consumption of fish.
